2 Claims. (01. --343) "This invention relates to improvements in a sleeping bag.

An object of this invention is to provide an improved structure which constitutes a sleeping bag, said structure including an upper and a lower panel arranged to be connected together along two edges thereof by a slide fastener and hingedly connected together along another edge of each, the lower panel of the pair having an envelope or pocket filled with a flexible filler and also having an inflatable section to provide resiliency, and the sleeping bag having a flap which constitutes a head rest with an inflatable pillow section, the flap being of such length as to be capable of being propped to such position as to constitute a canopy.

Ancillary objects and features of importance will become apparent in following the description of the illustrated form of the invention.

In the drawings:

Figure 1 is a perspective view of the device showing the head rest panel propped to the canopy forming position in phantom;

Figure 2 is an open perspective view of the device;

Figure 3 is a transverse view taken substantially on the line 33 of Figure l and in the direction of the arrows;

Figure 4 is a fragmentary longitudinal sectional view taken substantially on the line 4-4 of Figure 1 and in the direction of the arrows; and,

Figure 5 is a partially folded transverse sectional view of the flap which is so constructed as to form a head rest or a canopy.

As disclosed in Figure 2, the main parts of the device are a first or upper panel ill, a second or lower panel l2 together with a flap it The upper panel I0 consists of two sheets i8 and 28 of flexible material, for example, plastic, nylon or others. The sheets l8 and 20 are rectangular in form and are connected together at their edges by standard means, as fusing when commercial plastic is used or stitching if nylon is employed. Inasmuch as the panels :8 and 211 are connected together only at their edges an envelope or pocket is formed to accommodate the flexible filler 22 which may be fiberglass, waste or very light sponge rubber. Air vents protected by grommets 24 are provided in one of the sheets for ventilation of the interior of the envelope or pocket.

The lower panel I2 is made preferably of three sheets 26, 28 and 3B, the sheets being of the same material as the sheets 18 and 20. These sheets 26, 28 and 30 are also of a similar size and the sheet 26 is provided with air vents protected by the grommets 32.

Inasmuch as the three sheets 28, 28 and 30 are connected together at their free edges, two envelopes or pockets 36 and 33 are formed. The pocket 36 has a filler material ii! therein to serve the same purpose as the filler 22, but the pocket 38 accommodates a different material.

The pocket or envelope 3% is an inflatable section arranged to receive air under low pressure through the standard air inlet member 32 which has a valve to releasably retain the air in the inflatable section.

Inspection of Figure 3 illustrates that the pocket 38 is divided into several longitudinal chambers by connecting parts of the sheet 33 to portions of the sheet 28. However, the several chambers are connected together for air fiow by passages which are constituted by refraining from joining the sheets 36 and 233 the entire length of the panel iii.

A slide fastener 44 is arranged around two edges of the panel [2 and two edges of the panel It whereby the panels may be joined together along these edges after the panel it has been hingedly moved with respect to the panel 2 to such position that the panels are superposed.

In Figure 5 there is illustrated one edge of the upper panel It and a corresponding edge or" the lower panel i2. Fixed to the illustrated edge of the lower panel i2 is a flap l6 consisting of two sheets 48 and 50 of flexible material, as commercial plastic. These sheets constitute a panel and have a looped enclosure 52 at the outer end thereof constituting an inflatable section which is to be used as a pillow. A valved inlet member 54 is operatively connected with the inflatable section 52 for introducing air under pressure in this inflatable section.

To use the illustrated device, the slide fastener M is operated so that the panel i 2 may be swung away from the panel Hi to the position shown in Figure 2. The flap iii is removed and folded as disclosed in Figure 2. Then, the inflatable section 52 is charged with air, as is the inflatable section containing the compartments 38. After a person is disposed upon the fiberglass or other material filled envelope, the upper panel may be swung over and connected to the lower panel by the slide fastener.

In inclement weather the flap it may be unfolded and propped so as to constitute a hood.

When the device is not in use the flap may be inserted between the panels Ii) and i2 and the slide fastener 44 so actuated as to connect the panels together.

Having described the claimed as new is:

1. A sleeping bag comprising an upper panel of flexible material and a lower flexible panel hingedly connected to said upper panel, and a head rest flap connected to one edge of said lower panel, said head rest flap comprising a flexible panel of suflicient length to be propped to form a canopy and having an inflatable section to constitute a pillow when said head rest flap is rested upon a supporting surface.

2. In a sleeping bag which has a lower panel of flexible material, the improvement comprising a head rest flap connected to one edge of said panel, said head rest flap including a flexible panel of sufiicient length to be folded transversely, an inflatable section forming a part of said head rest flap and adapted to constitute a pillow which rests upon the folded head rest flap invention, what is 4 to elevate said inflatable section, and said head rest flap being sufliciently long to be propped up to form a canopy.
